Register Addresses
VEML6030 has actual six user accessible 16 bit command
codes.
The addresses are 00h to 06h (03h not defined / reserved).
Auto-Memorization
VEML6030 can memorize the last ambient data before
shutdown and keep this data before waking up.
When VEML6030 is in shutdown mode, the host can freely
read this data via read command directly.
When VEML6030 wakes up, the data will be refreshed by
new detection.
Note
• Command code 0 default value is 01 = devices is shut down
Command Code #0: Configuration Register
Register address = 00h
The command code #0 is for configuration of the ambient light measurements.
Note
• Light level [lx] is (ALS OUTPUT DATA [dec.] / ALS Gain x responsivity). Please study also the application note
